Jcodeharness MCP — questions

Answers built from our own checks of this server.

Is Jcodeharness MCP working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 85 of 92 checks got a reply (92.4%), average response time 1009 ms. The bar chart above shows every period we have measured.

The registry lists Jcodeharness MCP as active — why does it not respond?

The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.

How do I connect Jcodeharness MCP?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Jcodeharness MCP need an API key?

No. Jcodeharness MCP completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. This is what we observed, not what the docs claim.

How fast is Jcodeharness MCP?

It answers our handshake in 1009 ms on average, which is faster than 5% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is Jcodeharness MCP open source?

Yes — it is published under the NOASSERTION licence, written in JavaScript and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
